Diastolic blood pressure level falls over the early phases of sepsis, leading to a widening/expanding of pulse force, which is the distinction between the systolic and diastolic blood pressures. If sepsis results in being critical and hemodynamic compromise advances, the systolic force also decreases, producing a narrowing/decreasing of pulse force. https://codysybfi.wikiap.com/953016/plumber_fundamentals_explained
